Flexible Guts Used By Some Alaskan Trout For The Ultimate Binge Diet
2013-03-21 10:22:27

University of Washington Imagine having a daylong Thanksgiving feast every day for a month, then, only pauper's rations the rest of the year. University of Washington researchers have discovered Dolly Varden, a kind of trout, eating just that way in Alaska's Chignik Lake watershed. Organs such as the stomach and intestines in the Dolly Varden doubled to quadrupled in size when eggs from spawning sockeye salmon became available each August, the researchers found. They were like...

In Less Than 100 Years Trout Will Become Extinct In The Iberian Peninsula
2012-09-05 16:24:36

Climate change, pollution, the extraction of water for irrigation and overfishing all threaten the survival of the common trout. This fish is very sensitive to changes in its environment and, according to the Spanish study, its habitat will have reduced by half by the year 2040 and will have completely disappeared from Iberian rivers by 2100, so its population will become extinct. Global warming is threatening the existence of many fish species, especially those in the salmonid family,...

Fast-growing farm-raised salmon and trout that are sterile can now be produced using a method developed by Agricultural Research Service (ARS) scientists. Blocking reproduction can enhance growth, and is important for fish being reared in situations where reproduction is undesirable. The method allows researchers to more efficiently and reliably produce fish that have three sets of chromosomes, instead of the usual two sets. Fish with the extra set of chromosomes can't reproduce, so the...

Forestry access roads can have undesirable outcomes on fish populations living in remote lakes due to increased access, reveals research written by Len Hunt and Nigel Lester of the Ontario Ministry of Natural Resources, recently published in the journal North American Journal of Fisheries Management. The presence, location, and extent of forestry roads have important effects on access point development on remote lakes in northern Ontario. Due to the popularity of walleye in northern Ontario,...

Scientists say a synthetic chemical sex smell could help rid North America's Great Lakes of a devastating pest known as the "vampire fish." A laboratory version of a male sea lamprey pheromone was deployed to trick ovulating females into swimming upstream into traps, US researchers said. The vampire fish, known formally as the sea lamprey, has become a harmful parasite to native species of the Great Lakes since its accidental introduction in the 1800s. Recreational fishing of the Great Lakes...

GATLINBURG, Tenn. - Curious bears fattening up for winter craftily took part in a project to reintroduce native Southern Appalachian brook trout into streams in the Great Smoky Mountains National Park. Despite the interference, biologists completed the first phase of the planned reintroduction of the brook trout into several streams in the Tremont area of the park. From Sept. 7 to 19, the park closed an 8-mile segment of streams to poison nonnative fish. But bears tore into the baskets of...

PLYMOUTH - A restoration project intended to make Red Brook's spawning beds more accessible to fish populations resumes this week with the removal of New Way Dam. The project began with the removal of Robbins Dike in 2006. It is expected to be completed next summer with the dismantling of two other structures that control water flow and dredging to remove fill from wetlands. Red Brook, a five-mile stream on the Wareham-Plymouth border, runs from White Island Pond to Buttermilk Bay and is...

By Mark Armstrong Derwent Reservoir (Tel: 01207 255250): A great week in which five fish over 7Ibs were caught. All of these trout were landed from the South shore on power-bait and worm cocktails. Fish of the week weighed in at 10Ib 4ozs landed by G Smith, with Mr Richardson netting three trout weighing 7Ib, 4Ib & 3Ib. Sharpley Springs/Waters (Tel: 0191 5818045): Steady action this last week with natural patterns the order of the day. Top patterns have included "F" Flies, Sedge,...

By Scott Richardson;srichardson@pantagraph.com Two generations of the Niepagen family from Bloomington-Normal scored big on a recent fishing trip to Manitoba. Really big. They reeled in channel catfish that weighed 30 pounds and lake trout that topped that mark. At one point, they couldn't quit catching super-sized lake trout long enough to get some smaller ones for shore lunch. "It was pretty crazy," said Lee Niepagen. Wendell's brothers, Melvin and Norman, rounded out the foursome...
